Eukaryotes
Prokaryotic - no nucleus
Eukaryotic - nucleus
single cell and multicellular
Autotrophic - makes own energy
Heterotrophic - cannot make its own energy
Domain Eukarya
Cells are complex w/ more organelles than bacteria, or Archaea
most produce sexually, some asexually
includes kingdoms protista, fungi, plante, and Animalia
Kingdom Protista
different to define
all other Eukaryotic kingdoms evolved from a type of protist.
most are single cellular, do have complex organelles that bacteria and Archaea lack
Plant like protists
algae, kelp, phytoplankton are protists that photosynthesize. (responsible for 70% of Earth’s photosynthesis)
Animal-like protists
primary consumers that move toward prey
mostly aquatic
paramecium, amoeba, and intestinal parasites
wrap around, and digest prey
Fungus like protist
heterotrophs & decomposers
release enzymes to digest externally
reproduce using spores
Kingdom Plante
parasitic or carnivorous
sessile & multicellular
have cell walls, chloroplasts, and vacuoles
reproduce by spore and gamete formation
4 major groups
Non-Vascular Plants
bryophytes
most primitive (lack roots, stems, leaves)
NO vascular system
moist environment, low-lying & ground hugging
no seeds, reproduce via spores
(moss, hornwarts, liverwarts)
Seedless Vascular Plants
have vascular system, but don’t produce seeds
reproduce through spores
have true roots, stems, leaves
Gymnosperms
pollen delivers sperm to eggs by wind
seed that contains plant embryo, food supply (pine trees, spruce firs)
Angiosperms
have flowers
need pollinators (bees) for reproduction
make up most of our food crops
(cacti, roses, apple trees, shrubs
Kingdom Fungi:
Heterotrophs and Sessile (consumers)
cannot do photosynthesis
mostly multicellular
reproduce asexually or sexually using spores
Roles
can cause diseases (mold, mildew, athletes foot, diaper rash)
yeast (food)
antibiotics are made from Fungi
can have symbiotic relationships w/ organisms
Kingdom Animalia
all are multicellular, heterotrophs & mobile
most reproduce sexually, some asexual
respond to external stimuli
incredibly diverse
most are vertebrates or ocean dwellers
32 recognized phyla
Phylum Porifera (Sea sponge)
phylum cnidaria (jellyfish)
phylum plktyhelminthes (flatworms)
phylum annelila (segmented words)
phylum Mollusca (gastropods)
phylum arthropod
phylum echinodermata (sea stars, urchins)
* phylum chordata (dorsa nerve cord, notochord, post anal tail) (Humans)
phylum chordata - vertebrate
classification of fish
class amphibia
class reptillia
class aves
class mammaria
